pile in

Typically for the 'get-on-with-it' era, the railway and military worked like demons to restore the vital rail link. The crater was rapidly filled in and the earth tamped solid, the wreckage was removed by breakdown trains, new rails and sleepers were rushed forward by willing hands, and US Army bulldozers piled in. By 2020 on the same day, both tracks were open for traffic again where there had been a gaping pit just hours before.
